رواه ابن ماجه

It was narrated that Haani’ the freed slave of ‘Uthmaan ibn ‘Affaan said: when ‘Uthman ibn ‘Affaan stood by a grave he would weep until his beard became wet. It was said to him, “You remember Paradise and Hell and you do not weep, but you weep because of this?” He said, “The Messenger of Allaah (peace and blessings of Allaah be upon him) said: ‘The grave is the first of the stages of the Hereafter; whoever is saved from it, whatever comes afterwards will be easier for him, but if he is not saved from it, what comes afterwards will be worse for him.’” And the Messenger of Allaah (peace and blessings of Allaah be upon him) said: “I have never seen any scene but the grave is more frightening than it.”
